Answer:
f(-3)= -3
Step-by-step explanation:
We are given the function:
f(x) = 2x+3
and asked to find f(-3). Essentially, we want to find f(x) when x is equal to -3.
Therefore, we can substitute -3 for each x in the function.
f(x)= 2x+3 at x= -3
f(-3)= 2(-3) +3
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
Multiply 2 and -3.
f(-3) = (2*-3) +3
f(-3)= (-6)+3
Add -6 and 3.
f(-3)= (-6+3)
f(-3)= -3
If f(x)= 2x+3, then<em> f(-3)= -3</em>
Answer:
b
Step-by-step explanation:
if you subtract 5x then you will get y=-10-5x
You need the starting point and the end point and count how long it took to get to one point to the either
Answer:f(3) = 23
Step-by-step explanation:
2(3)² + 5√(3 - 2)
f(3) = 2(9) + 5√(1)
f(3) = 18 + 5(1)
f(3) = 18 + 5
f(3) = 23
